Dozirne pumpe

How do metering pumps work?

Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the metering line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering. 

Microprocessor technology since 1988

The accurate control of the pumps is made possible by microprocessor technology. Sophisticated monitoring functions ensure reliability in operation and minimum chemical consumption and optimum disinfection. Interfaces integrate the pumps into a fully automated process.

Over one million of our pumps are in use all over the globe, delivering reliable, accurate performance under the toughest conditions. Our proven design principles guarantee a high standard of quality and precision.
